UNITED STATES LAWRENCE J. KNITTEL, OF ROCHESTER, NEW YORK.

SKI BRAKE.

Application filed July 8,

To all whom it may concern:

Be it known that I, LAWRENCE J. KNIT- rnn, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Ski Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of the present invention is to prevent backward movement of a ski so that the wearer may successfully climb a hill or grade without experiencing the fatigue incident to a back slide at each forward stroke.

The invention consists of a pivoted brake which, on the forward stroke of the ski, rides over the snow and which at the limit of the forward stroke assumes a position to prevent backward movement of the ski.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an em bodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is a detail View in perspective of a ski embodying the invention,

F'gure 2 is a side View, the full lines showing the position of the brake when gliding over the snow and the dotted lines showing the position assumed by the brake to prevent backward movement of the ski,

Figure 3 is a detail view of the brake, and

Figure 4 is a detail perspective view of a modification.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates a ski which may be of any approved construction, the rear end being preferably beveled instead of square as usual. The brake is preferably applied to the rear end of the ski and consists of a plate 2 approximately the width of the ski and attached to the top side there- 1924. Serial No. 724,827.

of and having an upwardly and rearwardly inclined member 3 to the upper edge of which is hinged a member 4 which also corresponds to the width of the plate 2 so as to obtain an extended bearing against the snow and prevent any appreciable backward movement of the ski. Screws 5 or other fastening means are employed for attaching the brake to the ski, thereby admitting of the brake being readily applied or detached as required. The member 4 is loosely hinged to the member 3 so as to swing freely, whereby on the forward stroke of the ski, the member 4 rides upon the snow as indicated by the full lines in Figure 2, and at the limit of the forward stroke of the ski,the

member 4 assumes the position indicated by dotted lines in Figure 2, whereby to form an abutment to prevent backward movement of the ski, thereby making it possible to climb a hill or grade with a minimum amount of fatigue and exertion being experienced. The parts may be formed of any metal such as brass or aluminum which is strong and not susceptible to corrosion from moisture.

In the modification shown in Figure 4 the intermediate portion of the hinge knuckles between the plates 3 and 4 is cut away to expose the pintle 6 and a coil spring 7 is mounted upon the exposed part of the pintle and its ends engage the respective plates 3 and 4 where-by the spring 7 normally tends to hold the plate 4 against the heel or rear end of the ski 1.

hat is claimed is 1-- 1. A ski brake comprising an angular plate having a portion formed to be secured to the top of the ski, and another portion inclined upwardly and rearwardly, and a flat member loosely hinged to the top edge of the upwardly and rearwardly inclined portion of said plate.

2. In combination with a ski, a plate attached to the top side thereof adjacent the rear end and having a portion inclined upwardly and rearwardly to overhang the rear end of the ski, and a second plate loosely hinged to the top edge of the upwardly and rearwardly inclined portion of the first mentioned plate and of a length to project below the bottom side of the ski and adapted to operate to prevent backward movement thereof.

In testimony whereof I affix my signature.

LAWRENCE J. KNITTEL.
